HUNTB-470 - Blacked out from drinking... My female friend was on top of me when I woke up?!

Featuring Yui Tenma, Mirai Natsume, Minon Aisu, and Aima Ichikawa. I watched it because I like the first and last actresses, but it's not great that all four have the exact same plot. Bring a drunk guy friend home, he can't leave, so he stays over. Guy wakes up to a stained sheet and a half-naked female friend. No memory, but they clearly did it. Then she wakes up and they go for round two. Even if the lines aren't identical, the flow is way too similar.
